Only eleven days after the prediction news began rushing in; among many others reporting, MacRumors said on July 24th 2009:

The L.A. Times reports that Apple will begin allowing developers access to the tools they need to produce augmented reality applications starting with upcoming iPhone OS 3.1. [So far, AR applications] have used unpublished APIs which prevent them from being allowed on the App Store. Apple, however, told one developer that the tools necessary would become available with iPhone 3.1. [MacRumors]

In short, Apple is releasing their initial support to augmented reality applications. The Los Angeles Times posted the article that broke news that Apple told developers of the Nearest Tube AR train finder (Acrossair) that augmented reality apps will be allowed in the iPhone App Store in September, as predicted… let’s see if it turns out to be September 15th
